PFmatchit has a log flie which works in the background meaning that you don't need to save your work. This becomes a problem when someone open has opened your file while you are working on it and with out knowing it you are writing over top of each other. You can't save your versions unless you duplicate the whole node tree and move it to the side. It's seemly impossible to archive out a project because there isn't file associate with outside of the application.

I used PFmatchit for 4 months and thought the idea of the node based environment was really great. I liked the implementation of witness cameras and hints. But we found that it just wasn't a good tracker. I found that Nuke and Boujou would track the shot first time, but spend a lot more time in PFmatchit and it not track.

This will probably be a really good application at some point and the thinking is really good. But at the end of the day I just want the camera exported and PFmatchit didn't hold up in production.
